Get With The Guidelines-Stroke hospitals more likely to provide guideline-recommended treatment

Researchers found that GWTG-Stroke Performance Achievement Award (PAA) recognition hospitals were more likely to provide all recommended guideline-based care for patients, even if they didn't have Primary Stroke Center (PSC) certification. Hospitals with PSC certification also followed higher levels of adherence to stroke care guidelines.
